efi_loader: Fix warning in raw/cols query
The code to determine rows / cols on the screen could potentially run
into a case where it doesn't know how big the screen is. In that case,
assume 80x25.
Handles are not used at runtime. They are freed by the firmware when the
last protocol interface is uninstalled. So there is no reason to use EFI
memory when creating handles.

Here we do a couple of minor fixes like:
- Move .ivt section to the very beginning of the image
by default which allows us to use that image put right
at reset vector (usually 0x0)
- Improve relocation fix-up which became required once
we moved .ivt and understood a problem with existing implementation
where we relied on a particular placement of sections.
Now we don't care about placement because we just explicitly
check for .text and in case of ARCompact .ivt sections
- Re-implemnt do_reset() such that it calls reset_cpu() which
could implmented for a particular board
And hte most important part we introduce support for yet another
devboard from Synopsys - EMDK.

ARC: Improve relocation fix-ups
We used to have the one and only linker script for all ARC boards
and so we relied on a particular order of symbols there.
Because of that we used __ivt_end as the marker of the end of all the
code which won't be true any longer if we move .ivt section to any other
place. That said we'd better check for each section separately.
A couple of other improvements:
1. There's no point to include the marker of section end in interested
range because its address is beyond the section, i.e. we should
compare with "<" but not "<=".
2. .ivt section for ARCv2 cores is just an array of 32-bit ints and
they are not swapped even on little-endia cores while in case of
ARCompact cores .ivt contains valid code so swapping is required.
3. Just in case add check for ARC600 which is also ARCompact
and its .ivt is normal code.

exotic configs if the target board is not supposed to run Linux kernel.
